If it has 2 solenoids, then isn't one of them a dynamic braking/energy displacement solenoid?

I know - puzzling right? But a lever is a lever, so something is amiss - either the year, the voltage or its a highly re-worked cart. Because he indicated a "built-in" reducer maybe its a specific model like villager or tourall or something? But even those would have had only one solenoid on a series cart. I'm baffled. I think serial# is required to figure this out.
